Adaptive Optics Retinal Imaging in Inherited and Acquired Retinal Disorders

Genetic Disease | Inherited Disease

This is a Prospective Observational study. The aim of the study is to understand the underlying photoreceptor, retinal pigment epithelium or retinal vascular aberrations in inherited and acquired retinal disorders. The study would use adaptive optics (AO) technology to assist in-vivo visualization of these retinal structures and ascertain changes from normal. Further, by using the AO imaging in patients before and after treatments, this study aims to better understand the effect of various interventions and develop AO as an outcome measure in various retinal disorders.

Control group Inclusion Criteria:

1. Subjects aged 5 years - 70 years with normal eye examination.
